[tor-talk] TOR-Client bug?/wrong package size?

[bemoo129 at hushmail.com]

Hello,

Does anybody know how TOR deals with TCP-Pakets?

For example, while logging my outgoing traffic via iptables or 
wireshark, i saw a large amount of TLS-encrypted packages - but 
they all had a differend size, sometimes 60bytes, sometimes more 
then 1000.

In the TOR Documentation they explain, TOR will sent no normal tcp-
packets via a tcp-connection, but "cell" packets - with have a 
fixed size of 512 byte.

I would be very thankful if someoune could explain me, why i see 
different package sizes during sniffing my tor client`s traffic.

thx!
